PORTABLE HOIST.

sPEcIFI oA'rIoN forming part of Letters Patent No. 658.810, dated.October 2, 1960.

To all whom it may concern.-

7 Be it known that I, CYRUS H. SINCLAIR, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Portable Hoists,of whichthe following is a full, clear, and exact specification.

My invention relates more particularly to portable hoists designed forunloading vessels; and it has for its primary object to providea simpleand compact portable hoist capable of being readily folded when not inuse and as readily set up on the deck of the vessel or other surfacewhere it is to be used and securely held and braced while the cargo isbeing elevated from the hold and dumped into the lighter or otherdesired place.

' Another object of my invention is to provide improved andsimple meanswhereby the inclination of the runway upon which the bucket-carryingtrolley travels may be varied at will to suit the varying inclinationsof the deck or other surface on which the hoist is supported.

With these ends in view my invention consists in certain features ofnovelty in the construction, combination, and arrangement of parts bywhich the said objects and certain other objects hereinafter appearingare attained, all as fully described with reference to the accompanyingdrawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a vertical longitudinal sectional viewof my improved hoist, showing the same supported over the hatchway of avessel for unloading the same ontothe wharf or pier. Fig. 2 is anenlarged detail sectional view showing the bucket or holder in the actof releasing itself from the trolley. Fig. 2 is an enlarged transversesectional view of the runway and trolley. Fig. 2 is a detail view of ajoint for connecting the standards to a brace-rod hereinafter described.Fig. 3 is a vertical transverse section looking from the left-hand sideas viewed in Fig. 1,-and Fig. 4 is a plan view.

I have shown my invention in connection with a boat or vessel forunloading the same as an example of the many uses to which theinvention, may be put, this, however, being its greatest field ofusefulness at present known to me, owing to the great need of a suitablehoist that may be folded in a compact form and stowed away in the verylimited space that could ordinarily be spared on shipboard for anarticle of this kind.

1 represents a runway or track, which pref erably consists of an I-beam,the lower flanges of which serve as support-s or tracks for the rollers2 of a trolley 13, whose rollers are journaled on suitable pintlesprojectinginwardly from side plates 4, arranged on each side of theI-beam 1, as bettershown in Fig. 2. The trolley 3 is provided with ahook 5 or other support by means of which a bucket 6 or other holder forcontaining or carrying the material to be hoisted from the hold of thevessel and having a bail 7 or other equivalent device may be supportedfrom the trolley when it is desired to convey the bucket to the end ofthe runway and dump the material overboard and detached from the trolleywhen it is desired to lower the bucket into the hold to be again filled.The bail 7 may be provided with any suitable detachable device forsupporting it upon the book 5. I have shown it provided with a simplelink 8, which engages over the hook 5 when the bail is not otherwisesupported, but when the bail is lifted above the hook 5 the link 8 willdisengage therefrom. The upper end of the bail is attached to a chain orcable 9, which runs over a sheave or pulley 10, supported by a bracket11 from the under side of the beam 1, the other end of the chain passingaround a winch or drum 12, operated by a steam-engine or in any othersuitable way.

At or near one end of the beam 1 is secured a pair of inclinedstandards, which are telescopic or expansible and support the runwayupon the deck 13 in such a way that the inclin'ation of the runway maybe varied at will to suit the varying inclinations of the deck or othersurface on which the apparatus is to be supported. Each of thesestandards preferably consists of an upper tubular member 14 and a lowertelescopic member 15, inserted in the tubularmember 14 and held at thedesired adjustment by means of set-screws 16 or other suitable devices.The upper ends of the tubular members 14 are provided with" if etasio 4perforated ears 17 and the upper side of the runway or beam 1 with aperforated lug 18, and through these ears 17 and the lug 18 passes aremovable bolt or pin 19, whereby the runway 1 may not only be rotatedor in.- elined with reference to the standards 14 15, but the standardsmay be readily detached from the runway and folded together therewith ina compact form when it is desired to stow the apparatus away. The lowerends of the members 15 are pointed,so as to dig into the deck andprevent the inclined standards from slipping, and each of the members 14at or near its lower end is provided with a collar 20, which serves as asupport fora perforated lug 21, through which passes a bolt 22, having ahook 23 on its lower end, which passes downwardly through the hatch 24and engages with the inside of the deck, as clearly shown in Fig. 3, theupper end of the bolt 22 havinga nut 25, whereby the grip of the hook 23may be tightened and the standards 14 15 thus firmly clamped to the deckand held against both vertical and lateral movement at their lower ends.The upper end of each of the standards 14: is held against oscillationby a pair of guy-rods or cables 26, both secured at their upper ends toa collar 27, adjustably clamped to the tubular member 14 by set-screw28, while the lower end of each of the guys 26 is hooked to an eyebolt29, secured in the deck, and is also provided with a turnbuckle 30,wherebythe guy may be tightened.

By the means described it will be seen that one end of the runway may befirmly supported over the hatch and held against undue vibration in alldirections. In order to support the other end of the runway, I providethe same with a pair of standards similar to those already described andpreferably consisting of tubular members 31, receiving the pointedmembers 32, clamped therein to the desired adjustment by set-screws'33., while the upper ends of the tubular members 31 are secured to therunway by means similar to that already described with reference to theother standardst0 wit, a perforated lug 34:, formed on or secured to theupper side of the I-beam 1, and perforated sel, if to be used on a shipor Vessel, with the pulley 0r sheave 10 substantially over the hatch andthe lower end of the runway projecting over the side of the vessel. Thebucket 6 or other holder may then be lowered into the hold and drawn upby hand or by the steam-winch, as described, until the link 8 is at asufficient elevation to enable an operator who may stand upon adetachable platform 41, secured by suitable collars 42 to the members1-1 31, to place the link over and in engagement with the hook 5 of thetrolley, whereupon, the cable being paid out, the trolley runs down thetrack or runway and suspends the bucket or holder over the side of thevessel, whence it may be caused to dump in any suitable or well-knownway, the lower end of the I-beam 1 being also flanged vertically, asshown at 1, to prevent the trolley from falling off. The bucket dumped,the trolley is drawn back into the upper end of the runway until theupward lift on the bail 7 disengages the link 8 from the hook 5, or, asbefore explained, such bail may be disengaged from the hook 5 by any ofthe improved hook devices well known in the art, and when oncedisengaged the bucket is again lowered into the hold, and so on.

When the device is not needed for use, the standard members may betelescoped one within another, thus reducing their length, and entirelydetached from the I-beam 1, as also from the platform 41 and clamp-bolts22, and the parts thus separated folded lengthwise in a neat and compactbundle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
